Abstract
A series of nanocrystalline Sn4+ substituted NiFe2O4 with general formula Ni1+xSnxFe2-2xO4 (x = 0.0, 0.1, 0.2, 0.3, 0.4, and 0.5) has been prepared by co-precipitation synthetic method. The prepared compounds have been sintered at 1000 degrees C. The structural and microstructural evolutions of the nanophase have been studied by X-ray powder diffraction and the Rietveld method. The X-ray diffraction patterns showed that all the samples have cubic structure with the space group Fd-3m.Specific structural parameters were obtained by X-ray diffraction (XRD) spectra fitting refinement using the Rietveld method. Microstructure characterization by TEM corroborates the findings of X-ray analysis.
